  • GPS speed
  • Vertical speed
  • Altitude
  • Glide Ratio
  • Distance to Take-Off/Waypoint
  • Compass, direction to Take-Off/Waypoint

Ultra-sensitive altimeter-variometer

The Varduino GPS combines an ultra-sensitive pressure sensor (10cm resolution, 50 measurements/second) and an advanced signal filtering algorithm to provide the user with an unprecedented reactivity.

A 1W speaker with class-D amplifier is built-in for more natural vario sounds and voice notifications.

Cross-Country Flying

Varduinos are equipped with a GPS chip (GPS, GLONASS, Galileo, QZSS) and a 8Go micro SD card, which offer:

  • IGC flight recordings. A FAI signature can be obtained by using LogFly to downlad the file from the variometer. The number of logs is almost unlimited using a SD cad.
  • Loading Oziexplorer waypoint files for XC navigation or paraglidiing competitions. The current setting for WP radius is currently 200m.

Connectivity: Bluetooth and USB

The Varduino GPS can be connected to Android and iOS smartphones and tablets through Bluetooth thanks to its Bluetooth 4.2 low-energy chip

The most popular applications are compatible, such as:

  • XCtrack
  • XCSoar
  • Flyskyhy

GPS and pressure data are transmitted via Bluetooth. Many data formats are available and can be configured using Varduino Manager.

The Varduino GPS shows up as a mass storage device on both Windows 10 and MacOS. IGC tracklogs can therefore be easily dowloaded from the SD card and waypoint files can be easily copied to the SD card


The Varduino GPS features a 2500mAh LiPo battery with a flight autonomy of about 30h at maximum volume. The battery can be charged from USB and the charge status is updated on the display even when the device is off.


The Varduino GPS is filly compatible with Varduino Manager. Its sound profile as well as all settings can be easily configured from your computer.
